通过学习借鉴朋友的实现方法进行整理，实现了PHP版的微信公共平台消息主动推送，分享给大家供大家参考，具体内容如下

此方法是通过模拟登录微信公共平台的方法来实现的。

代码如下：

一、登录接口部分代码

//登录

private function login(){

$url = 'https://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN';

$this->send_data = array(

'username' => $this->_account,

'pwd' => md5($this->_password),

'f' => 'json'

);

$this->referer = "https://mp.weixin.qq.com/";

$this->getHeader = 1;

$result = explode("\n",$this->curlPost($url));

foreach ($result as $key => $value) {

$value = trim($value);

if(preg_match('/"ErrCode": (.*)/i', $value,$match)){//获取token

switch ($match[1]) {

case -1:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"系统错误")));

case -2:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"帐号或密码错误")));

case -3:

die(urldecode(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>urlencode("密码错误")))));

case -4:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"不存在该帐户")));

case -5:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"访问受限")));

case -6:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"需要输入验证码")));

case -7:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"此帐号已绑定私人微信号，不可用于公众平台登录")));

case -8:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"邮箱已存在")));

case -32:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"验证码输入错误")));

case -200:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"因频繁提交虚假资料，该帐号被拒绝登录")));

case -94:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"请使用邮箱登陆")));

case 10:

die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"该公众会议号已经过期，无法再登录使用")));

case 0:

$this->userFakeid = $this->getUserFakeid();

break;

}

}

if(preg_match('/^set-cookie:[\s]+([^=]+)=([^;]+)/i', $value,$match)){//获取cookie

$this->cookie .=$match[1].'='.$match[2].'; ';

}

if(preg_match('/"ErrMsg"/i', $value,$match)){//获取token

$this->token = rtrim(substr($value,strrpos($value,'=')+1),'",');

}

}

}

二、信息发送部分代码

//单发消息

private function send($fakeid,$content){

$url = 'https://mp.weixin.qq.com/cgi-bin/singlesend?t=ajax-response&lang=zh_CN';

$this->send_data = array(

'type' => 1,

'content' => $content,

'error' => 'false',

'tofakeid' => $fakeid,

'token' => $this->token,

'ajax' => 1,

);

$this->referer = 'https://mp.weixin.qq.com/cgi-bin/singlemsgpage?token='.$this->token.'&fromfakeid='.$fakeid.'&msgid=&source=&count=20&t=wxm-singlechat&lang=zh_CN';

return $this->curlPost($url);

}

三、群发信息代码

//群发消息

public function sendMessage($content='',$userId='') {

if(is_array($userId) && !empty($userId)){

foreach($userId as $v){

$json = json_decode($this->send($v,$content));

if($json->ret!=0){

$errUser[] = $v;

}

}

}else{

foreach($this->userFakeid as $v){

$json = json_decode($this->send($v['fakeid'],$content));

if($json->ret!=0){

$errUser[] = $v['fakeid'];

}

}

}

//共发送用户数

$count = count($this->userFakeid);

//发送失败用户数

$errCount = count($errUser);

//发送成功用户数

$succeCount = $count-$errCount;

$data = array(

'status'=>0,

'count'=>$count,

'succeCount'=>$succeCount,

'errCount'=>$errCount,

'errUser'=>$errUser

);

return json_encode($data);

}

四、获取所有用户信息代码片段

//获取所有用户信息

public function getAllUserInfo(){

foreach($this->userFakeid as $v){

$info[] = $this->getUserInfo($v['groupid'],$v['fakeid']);

}

return $info;

}

//获取用户信息

public function getUserInfo($groupId,$fakeId){

$url = "https://mp.weixin.qq.com/cgi-bin/getcontactinfo?t=ajax-getcontactinfo&lang=zh_CN&fakeid={$fakeId}";

$this->getHeader = 0;

$this->referer = 'https://mp.weixin.qq.com/cgi-bin/contactmanagepage?token='.$this->token.'&t=wxm-friend&lang=zh_CN&pagesize='.$this->pageSize.'&pageidx=0&type=0&groupid='.$groupId;

$this->send_data = array(

'token'=>$this->token,

'ajax'=>1

);

$message_opt = $this->curlPost($url);

return $message_opt;

}

//获取所有用户fakeid

private function getUserFakeid(){

ini_set('max_execution_time',600);

$pageSize = 1000000;

$this->referer = "https://mp.weixin.qq.com/cgi-bin/home?t=home/index&lang=zh_CN&token={$_SESSION['token']}";

$url = "https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize={$pageSize}&pageidx=0&type=0&groupid=0&token={$this->token}&lang=zh_CN";

$user = $this->vget($url);

$preg = "/\"id\":(\d+),\"name\"/";

preg_match_all($preg,$user,$b);

$i = 0;

foreach($b[1] as $v){

$url = 'https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize='.$pageSize.'&pageidx=0&type=0&groupid='.$v.'&token='.$this->token.'&lang=zh_CN';

$user = $this->vget($url);

$preg = "/\"id\":(\d+),\"nick_name\"/";

preg_match_all($preg,$user,$a);

foreach($a[1] as $vv){

$arr[$i]['fakeid'] = $vv;

$arr[$i]['groupid'] = $v;

$i++;

}

}

return $arr;

}
